Neodoxy,
No, I think I understand what you are trying to say, I just disagree.
Bastiat said long ago, that the difference between a good economist and a bad economist is: the second only takes anto consideration “that which is seen” (like the hospitals and bridges built by government)
And the good economist considers all the effects, before during and after the act.
You start your argument with “If the government raises a large amount of taxes” … then it can choose to spend it either “wisely” or frivolously and this will
impact the economy and capital investment. What you cannot see is the number of hospitals that would have been built if the government did not tax the citizens.
That is unseen and incalculable.
But before a government can collect a large amount of taxes, it has to take that exact amount of money out of the current or future economy. It has to "subtract "capital investment out of circulation in the free market to create the impression that it is adding to capital investment.
Governments cannot generate productive income, it can only redistribute to less efficient avenues.
Then after they do that, they further corrupt the economy and capital investment by interfering and competing with free market forces. This increases cost to consumers, lowers quality to consumers in exactly those markets they are trying to “help” and it contracts or even kills marginal competitors right out of the market, reducing furure capital investments.
Further they are incapable of spending wisely, because they do not compete for customers like the rest of us and by definition they are notoriously inefficient. Only Keynesians believe that there is such a thing as “government investment”
Flying Axe,
There are many examples of where lowering tax rates improved the economy and even increased tax revenue, because more people were employed and paying the lower rate and causing the economy to expand. Unfortunately as with any history, people with opposing interpretations will just say you are wrong and find other reasons to explain it.
